import sensor
import time
import mjpeg
import machine

sensor.reset()  # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565)  # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA)  # Set frame size to QVGA (320x240)
sensor.skip_frames(time=2000)  # Wait for settings take effect.

led = machine.LED("LED_RED")

while True:
    
    led.on()
    m = mjpeg.Mjpeg("example.mjpeg")
    
    clock = time.clock()  # Create a clock object to track the FPS.
    for i in range(5*60*30):
        clock.tick()
        m.add_frame(sensor.snapshot())
        print(clock.fps())
    
    m.close(clock.fps())
    led.off()
    
    print("saved")
